Integrated technology (it) estimation modeling

ABSTRACT

In general, the present invention provides a technique for IT estimation modeling of any organization. Although this estimation model is applied to SOA herein, it is not limited to solely estimating SOA activities; the maturity-based estimation modeling can be applied to other areas and disciplines, even beyond the IT industry. The maturity-based model of the present invention also offers executives and project managers a very effective estimating tool to analyze the impact of project variances. Resources do not need to be taken off projects and assigned to perform estimations, as this model acquires knowledge over time and delivers ever more precise estimates with each successive project. Executives and project managers may analyze the effects of additional staff, function changes, or other events to an overall project. Additionally, new projects may be estimated without utilizing current personnel with this adaptive learning model.

FIELD OF THE INVENTION

In general, the present invention relates to estimation modeling. Specifically, the present invention relates to IT estimation modeling.

BACKGROUND OF THE INVENTION

Today's IT estimation techniques are simplistic in nature and are not well-suited for generating precise estimates for service-oriented projects. Service-oriented estimation requires the inclusion of additional factors in order to derive accurate project estimates. Specifically, the current estimation techniques and models do not take into account several variances (for example, culture, readiness, and organizational change, to name a few) which if not addressed have a significant impact on the reliability of the estimates. In fact, these variables in present estimation approaches must be discovered and accounted for in the form of new tasks without taking into account the impact to the estimation model if the task is not completed on time or satisfactorily. Such an approach often fails to account for the cultural adoption needed for the methods to be useable and, worse, the estimation model cannot account for the fact that the team has not adopted the methods which is an assumption in the estimation model.

Service-oriented architecture (SOA) requires a framework or estimation model which allows and recognizes both the specific tasks that must be completed as part of a project or program while taking into consideration both transformational goals often required as part of the project and maturity of the organization which will both implement and use the solution being estimated.

Drawbacks of known solutions include, among others, the following: primary focus on effort required for IT solution development/construction; focus only on development of IT components to fulfill the current set of requirements; a failure to take into account organizational maturity and skills maturity; factors that influence reduction in effort over time are not considered for estimation purposes; and the impact of re-factoring and reuse is not considered during estimation.

I. General Description

In general, the present invention provides a technique for IT estimation modeling of any organization. Although this estimation model is applied to SOA herein, it is not limited to solely estimating SOA activities, the maturity-based estimation modeling can be applied to other areas and disciplines, even beyond the IT industry. The maturity-based model of the present invention also offers executives and project managers a very effective estimating tool to analyze the impact of project variances. Resources do not need to be taken off projects and assigned to perform estimations, as this model acquires knowledge over time and delivers ever more precise estimates with each successive project. Executives and project managers may analyze the effects of additional staff, function changes, or other events to an overall project. Additionally, new projects may be estimated without utilizing current personnel with this adaptive learning model.

Our innovation takes into consideration additional factors over and above today's estimation techniques. These additional factors include maturity aspects of several factors that influence solution development and deployment efforts. A maturity assessment is initially performed and maturity level scores are assigned. The maturity level scores will ensure that consistent and accurate estimates are generated and the impact of improving maturity levels can be determined via new estimations. The estimation model also takes into consideration business services, function, infrastructure, and maturity levels of: an organization's skill level, technical environment, and technical complexity. The maturity assessment assignment takes into consideration both the organizational maturity level and the maturity level of any third party firm that will participate in the project. The composite maturity rating will be used in the estimation modeling. In the event that there is not a third party firm, the organization's own maturity ratings will influence the estimations.

This model can be used to perform assessments of whether additional training or bringing in subject matter experts would have a significant impact on project durations, schedule recovery, or costs. Advantages of using our invention include, among others:

-   -   1. Minimizing the use of assumptions which have unintended         consequences on the estimate. Often estimates are unrealistic         or, worse, known to be false at the time of the estimate and are         in place solely to provide a means of citing why the estimate is         faulty when more information is known. In addition, teams often         cannot reliably determine the assumptions that underlie their         estimates since no objective framework exists for them to use.         Our solution remedies this problem by providing a maturity-based         effort contingency measurement moderation framework, which         accounts for the variables which get translated to assumptions.         In addition, our invention requires the performance of an         assessment as part of the estimation process providing         additional and necessary information to create a reliable         estimate.     -   2. Projects leveraging or adopting SOA often are part of larger         transformational initiatives or have business goals which are         expected to be realized incrementally. Our invention accounts         for both short and long-term desired benefits. As a result, the         incremental costs associated with transformation can be         identified and an informed choice made as to whether to include         or omit specific goals from a project. This is in contrast to         present approaches where the long-term goals are compromised on         a project due to cost, but not determined until the project is         largely completed.     -   3. Provides a customizable framework and measurement metrics to         provide consistency and common understanding of required factors         to be estimated for projects which are first of a kind, or         projects which must be done due to market forces but carry a         considerable risk.

Additional areas where this tool can be used are:

-   -   For project impact analysis as opposed to its original intended         use for project estimation modeling.     -   Team leaders or executives can modify assumptions to determine         impacts on tasks and activities.

Referring to FIG. 1, a block diagram 10 depicts the approach of the present invention. Specifically, the Maturity-based Estimation Model (MBEM) approach to estimation works on a multi-step process which allows for identifying the base estimates (baseline count). Then, we apply the calculated percentage impact based on the maturity of these organizational and business contingency criteria. The base estimates are a sum total of the service points calculated from the effort estimation of the solution and project factors and the business services factors.

Realization of a SOA is the realization of loosely coupled services which have externalized service descriptions. In addition, the implementation details of these services are completely hidden from the consumers of these services. The modeling of these services is achieved by rising the level of abstractions of the well-known modeling constructs like object-oriented analysis and component modeling. The focus of modeling, design, and implementation of services is based on identifying the functional and non-functional aspects of the services and the interface specifications required at the right level of abstraction.

The proposed estimation model defines an approach for estimating the effort required to realize services in a SOA. The proposed estimation model raises the level of abstraction for effort estimation with a focus on services. The effort required to define, design, and implement services is used as a foundation for this overall model. In addition the model also considers aspects of service maturity as a key contingency factor along with a number of others to define a much more comprehensive approach and technique for estimating the effort required to realize services and thereby a SOA.

Existing estimation techniques were focused on number of objects, components, and integration interfaces and the effort required for realizing each of these aspects of the overall solution. In addition these estimating techniques had no notion of solution maturity including organizational or resource maturity.

The proposed model leverages the techniques available in these existing techniques, but provides for a more comprehensive approach for effort estimation with a focus on a number of contingency factors including maturity.

This model could be effectively adapted to estimate the effort required for solutions other than those based on Service-Oriented Architecture.

Calculating the Net Estimates

Referring to FIG. 2, a block diagram 20 describing the calculation of net estimates under the present invention is shown. Under the present invention, it is assumed that the solution and project factors measure the functional aspects of the solution in context, and the related information and integration issues involved. The business services factors address the measurement of various factors that address the business services deployment and management layer of the solution. The contingency criteria are measured based on the maturity of the various factors that have potential impact on the delivery and deployment of this shared services initiative from the view of business, organizational, and business services non-functional factors point-of-view.

Also under the present invention, the baseline count or the base estimates are constituted by a sum total of Service Points from the project and solution factors and the business services factors.

Baseline Count Calculation

The Baseline Count is the foundation for the overall effort estimation model. The Baseline Count includes two key aspects including the Business Services Factors and the Solution and Project Factors. The Business Services Factors, as the name implies includes a set of criteria that are business focused and influence the Solution and Project Factors. The Solution and Project Factors based on these Business Services Factors enable the determination of the overall Baseline Count and thereby the effort estimation of software projects in general and SOA projects in particular.

The Business Services Factors include (among others) the: number of Business Goals; number of Business Processes identified for business transformation; and number of Business Activities or Business Process Tasks associated with the business processes.

The Business Goals that influence the overall Baseline Count are those that directly impact the IT transformation or those that can be automated. Sales Targets, Marketing Targets and other similar ones which directly do not influence the transformation or automation are not included in the overall set considered for estimation. The KPI's and metrics associated with the Business Goals enabling IT transformation and automation also play a significant role in the overall estimation model. These KPI's influence the non-functional aspects of the solution and are leveraged for determining the contingency factors described later as part of the overall estimation model. Business Processes directly influence the overall Baseline Count required for effort estimation. The number of Business Processes and the Business Activities or the Business Process Tasks together enables the determination of the Project and Solution Factors. The business processes are a high level view of a business and the associated business activities provide a view of the different tasks required to complete a business process.

The Solution and Project Factors include (among others) the; number of probable and/or identified services; number of probable and/or identified service compositions; and number of Integration Points—Data, internal and external. The Number of Services is the actual number of services required for realization of the overall SOA solution. These are determined based on the actual number of business goals, the business processes, and the associated business activities. The overall Baseline Count, which is the foundation for the overall estimation model is equal to the total effort required to realize all the services required in the overall solution. The total effort required for the realization of all the services can be determined by individually estimating the effort required to implement each of the services. The total effort (in hours) required to realize each service is dependent on a number of factors including the: number of resources required for implementing a given service; number of hours for each resource over the entire solution delivery lifecycle for a given service; and total number of hours required by all the resources for a given service. Each resource may require a different number of hours to complete the tasks to realize a given service. The total effort required to realize each service is the sum of the hours of effort required by all the resources identified for a given service.

In addition, the services can be categorized, for example, as low, medium and high, based on the complexity of the services. The total estimated effort for realization of a single service can be associated with a category like “low complexity” and the effort for the other categories can be related to the base category as a multiple of the factor of complexity. This is depicted as follows:

Total Effort Required for each Service Implementation=(Complexity Factor×Estimated Effort from Above)

As such, for:

Low Complexity Services, Complexity Factor=1

Medium Complexity Services, Complexity Factor=1.4

High Complexity Services, Complexity Factor=1.8

For a solution with less complexity, a categorization of services may not be essential. Also extremely complex solutions may warrant more categories. In addition these categories can be associated with a suitable complexity factor which can be calibrated.

In addition, the resources required may include a number of resource types which include Service Designers, Service Developers, Testers and Project Managers, and they participate in the overall solution delivery lifecycle during different phases including solution definition, design, implementation, testing, and deployment. These resource types would have no impact on the overall estimates.

Total Effort for Realization of all Services=Effort for Service 1,+Effort for Service 2+Effort for Services N . . . .

Baseline Count=Total Effort Realization of all Services. Once the Baseline Count is calculated, then the contingency factors or contingency scores are determined and applied to the Baseline Count to calculate the final estimate for the overall solution. This is described in the remaining sections.

As the first step of calculating the contingency scores, the maturity scores (% impact) of each of the factors from the contingency criteria are aggregated at the individual criteria. Then, we apply the weighted factor to each of the contingency gross scores to arrive at a contingency allocation score.

The default estimation model contingency factor allocation score is as follows:

Contingency score allocation table Moderation Contingency criteria Allocation Shared Services non-functional 33.33% Complexities Organizational Contingencies 33.33% Business Adoption Contingencies 33.34%

The user (organization) applying this estimation model can modify this allocation table depending on their organizational environment factors including organizational maturity that impact such initiatives in consideration. This helps fine-tune this estimation model depending on the degree of relevance of each of these criteria within the organization for such initiatives.

Next, each of the criteria measurement is taken and the maturity of the various factors within each of the factors is assessed and the respective factors are rated. FIG. 3 shows a sample pre-filled measurement factor maturity assessment and scoring template 30. Template 30 includes factor descriptions 32, degrees of maturity 34, assessed maturity 36, and score impact 38.

As the very next step, we take the % Score Impact from each of the assessed factor, and aggregate them within its respective criteria. Then, we take the gross contingency score and apply the moderation allocation percentages to ensure the skew of the respective criteria based on the customized organizational environment.

Business Services non-functional Complexities Score=Sum total of “% Score Impact” column from Factors that belong to this criteria.

Organizational Contingencies Score=Sum total of “% Score Impact” column from Factors that belong to this criteria.

Business Adoption Contingencies Score=Sum total of “% Score Impact” column from Factors that belong to this criteria.

Some representative factors for these contingency criteria are identified below:

a. Business Services non-functional Complexities

-   -   Number of provider applications (service implementations)     -   Number of design time service composites     -   Provider Application(s) complexity     -   Number of inputs or service end-points (testing only)     -   Compliance with Service Level Agreement including service         availability, reliability, and performance     -   Cross application security requirements such as encryption,         authentication, and authorization         b. Organizational Maturity Contingencies     -   Organizational skill level in deploying and managing SOA         approach and implementations     -   Business ownership of IT initiatives     -   IT strategy alignment with business goals     -   Organizational structure     -   SOA Skills and resource availability         c. Business Adoption Maturity Contingencies     -   Compliance with regulatory requirements     -   Compliance with industry and technical standards

The next set of steps are focused on using the base estimates, applying the moderation scores on the contingency and complexity criteria scores, and arriving at the net estimates for the overall initiative.

Gross Contingency Score=Shared Services non-functional Complexities Score+Organization Contingencies Score+Business Adoption Contingencies Score

Shared Services non-functional Complexities Moderated Score=(Shared Services non-functional Complexities Score/Gross Contingency Score)*Moderation Allocation % for this criteria

Organizational Contingencies Moderated Score=(Organizational Contingencies Score/Gross Contingency Score)*Moderation Allocation % for this criteria

Business Adoption Contingencies Moderated Score=(Business Adoption Contingencies Score/Gross Contingency Score)*Moderation Allocation % for this criteria

Contingency Gross Score=Shared Services non-functional Complexities Moderated Score+Organization Contingencies Moderated Score+Business Adoption Contingencies Moderated Score

The base estimates (Service Points) are now multiplied with the sum total of % impact scores (Contingency Gross Score) accumulated from the moderation calculations.

Total Effort Estimates=Base Estimates+(Contingency Gross Score*Base Estimates)

Allocation Net Estimates Allocating Engagement Phases

Once we arrive at the Net Estimates we can now apply and allocate these estimates to the various engagement phases that apply here. Here again this estimation model offers a baseline engagement phase structure and can be customized to suit the user organization's methodology. In addition, the percentages allocated to the different phases can be customized based on the organizational maturity. For example, in the case of a more mature organization, Build may require 20% of the effort versus Requirements and Design requiring more emphasis.

FIG. 4 outlines the phases of a typical engagement. As can be seen, the phases include planning 40, requirements definition 42, design 44, build 46, testing 48, and deployment 50. Next, we take the allocation percentages and allocate Total Effort Estimates among the various phases as per the following:

Planning Estimates=Net Effort Estimates*Planning Allocation %

Requirement Estimates=Net Effort Estimates*Requirements Allocation %

Design Estimates=Net Effort Estimates*Design Allocation %

Build Estimates=Net Effort Estimates*Build Allocation %

Testing and Deployment Estimates=Net Effort Estimates*Testing and Deployment Allocation %

Allocating Net Estimates to Resources and arriving at FTE estimates

Once the allocation to the respective Engagement Phases is done, we now use the Estimation Model Resource Allocation ratios, and allocate the effort estimates to the respective resources by phases. The suggested allocation is once again the standard % allocation, and is modifiable based on an organization's environment maturity and related factors.

Referring to FIG. 5, a method flow diagram 60 is shown. As depicted step S1 is to estimate the effort required to realize each of a set of services within an IT infrastructure. Step S2 is to identify and apply a service complexity factor to each effort estimated. Step S3 is to identify and estimate a set of business service factors for each of the set of services. Step S4 is to estimate a baseline count for each of the set of services using the set of business service factors. Step S5 is to identify a set of service contingency factors for the set of services, and estimate an overall service contingency factor base on the set of service contingency factors. Step S6 is to estimate an effort for each service realization based on the overall baseline count and the set of service contingency factors. Step S7, is to estimate an overall effort to realize all of the set of services collectively.
